# Unreal Chemist vs Science Simulations

The clearest difference is in-app purchases: Science Simulations at none against Unreal Chemist's 1. Science Simulations also leads on ads (none vs shown) and review sentiment (100% vs 73%). Unreal Chemist's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (68 vs 4). On price and device support there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase. Science Simulations asks for nothing beyond the download.

Science Simulations holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Unreal Chemist has 68 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 73% of Unreal Chemist's written reviews are positive against 100% of Science Simulations's.

Unreal Chemist ships an update every 2 weeks, Science Simulations every 2 months. The most recent releases landed on October 20, 2026 and October 25, 2026 respectively.
